GEARING.

SPECIFICATION forming part of Letters Patent No. 663,531, dated December11, 1900.

Application filed January 15l 1900. Serial No. 1,458. (No model.)

To all whom, it may concern:

Beit known that-LEDWARD R. BALEs,a citizen of the United States,and aresident of Centralia, in the county of Marion and State of Illinois,have invented new and useful Improvements in Gearing, of which thefollowing is a full, clear, and exact description.

This invention relates to a gearing adapted especially to automobilevehicles, the object being to provide means for transmitting the drivingpower from the motor on the vehiclebody to the traction-axle, whichmeans will not be influenced by the movement of the vehicle-bodyindependently of the drivingaxle.

This specication is the disclosure of one form of the invention, whilethe claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a plan view of the gearing. Fig. 2 is a longitudinal sectionthereof on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3of Fig. l. Fig. 4 is a section on the line 4 4 of Fig. 1, and Fig. 5 isa section on the line 5 5 of Fig. 2.

The shaft 6, which is the prime mover, being driven from the motor, ismounted to turn in boxes 7, which are fastened rigidly to thevehicle-body, parts of which are indicated at 8 in Figs. 1 and 3. Theboxes 7 are formed with inwardly-directed tubular extensions 7F,respectivelysurrounding the shaft 6 and having the arms of a yoke 9mounted loosely thereon, so as to permit the voke to 'swing on the boxes7 concentricallywith the axis of the shaft 6. The yoke 9 has avertically-extended tubular stanchion 10 formed thereon, which providesa bearing for the revoluble shaft 11, constituting the axis of amiter-gear 12, which is fastened to the lower end of the shaft 11 withinthe yoke 9 and which is driven from the shaft 6 by a miter-gear 14, asshown. It will be seen that as the yoke 9 swings around the shaft 6 themesh of the gears 12 and 14 is not interrupted and that the gear 12 willbe driven uniformly notwithstanding the movement of the yoke 9.

A box 15, carried rigidly on an arm 16, is

mounted on the tubular stanchion 10, permitting the arm to tu rn freelyaround the stanchion. This arm 16 carries an elongated tubular box 17,in which is fitted to turn a corresponding box 18, the latter box beingcarried on an arm 19, similar to the arm 16. The parts 17 and 18 beingheld from sliding on each other, but being free to turn relatively, itwill be seen that the arms 16 and 19 are connected securely together insuch a way as to permit them to have, however, relative turning orswinging movement. Within the box 1S is mounted to turn a shaft 20,carrying at one end a mitergear 21, which is meshed with the gear 12, sothat the shaft 20 is driven from said gear, and consequently from theprimary movement or drive shaft 6. Now it is clear that the arms 19 and16, with the shaft 20 and gear 2l, may turn around the axis ofthetubular stanchion 10 and that this movement will not interrupt the meshof the gears 21 and 12.

The arm 19 carries a box 22, which is similar to the box 15 and whichhas mounted to turn therein a tubular stanohion 23, similar to thestanchion 10. The tubular stanchion 23 is formed on a yoke 24,corresponding with the yoke 9, and the tubular stanchion 23 forms abearing for the revoluble shaft 25, which carries at its lower end,within the yoke 24, a miter-gear 26. The yoke 24 has a countershaft 27mounted in the arms thereof at right angles to the shaft 25 and inposition to be driven from the gear 26 through the medium of abevel-gear 28, meshing with the gear 26. The adjacent end of the shaft2O has a bevelgear 29 fastened thereto, and this gear 29 meshes with thegear 26 to drive the same. On the axle 30 of the vehicle is carried toturn a frame 31. The axle may be fitted with the usual compensating ordifferential gear contained in a box The frame 31 has transverselydisposed extensions 31a, forming bearings for trunnions 24, formed onthe yoke 24 concentric with the axis of the shaft 27, and in whichbearings the trunnions 24al are mounted to rock. The axle 30 is drivenfrom the shaft 29 through the medium of a pinion 33, fastened to theshaft 29, and a spurgear 34, fastened to the axle 30. The spurgear 34 ishere shown as fast to the box 32,

IOO

same is true of the connection of the shaft 6 with the motor.

By means of this gearing the motor may b mounted on the vehicle-body andits force transmitted to the driving-axle of the vehicle by a positiveall-gear connection and without the intervention of chains and otherflexible devices, which are disadvantageous, as is well known. Thevarious parts which carry the gearing above described are so joined thatthey will accommodate themselves t-o all of the movements of thecarriage-body independently of the runnin g-gear, th us relieving theshafts and cog-wheels of all strain due to these movements and providinga gearing which runs positively and with perfect ease during themovement of the vehicle. It will be seen that the shaft 6, having afixed bearing on the vehicle-body, and the axle 30, hav- Ving a fixedbearing on the running-gear, may

move relatively in a variety of different directions. The whole gearingmay be swung bodily around the extensions 7a and concentrically to theshaft 6. The whole of the gearing may also be moved bodily around theaxis of the shaft 27 and bodily around the axis of the axle 30. tively,at the ends of the shaft 2O may turn relatively to each other around theaxis of the shaft 20, owing to the rolling or turning connection betweenthe tubular bearings 17 and 18, and the yokes 9 and 24, with theshaft 6at the yoke 9 and the shafts 27 and 30 at the yoke 24, may be turnedindependently of the shaft 2O and its gears 21 and 29 on axes coincidentwith the axes of the shafts 1l and 25. All of thesemovements may beeffected freely and to any degree without in any way disturbing theproper mesh of the various gears, and consequently without aectin g thetransmission of the power from the motor to the driving-axle.

I desire it understood that I do not consider myself conned to theprecise arrangement of parts which I have here illustrated, but believeI am entitled to protection on the novel combinations of elements asdefined in my claims.
